|Aphanocladium species are common, but comprise a small proportion of the fungal biota. Spores are dry and are designed for wind dissemination. This very delicate genus is somewhat related to Beauveria and Engyodontium. No information is available regarding health effects, or toxicity. Allergenicity has not been studied. Identified in air by culturable (Andersen) sampling. Spores are not distinctive on spore trap samples and would be categorized as "other colorless." Recorded sources of isolation are from other fungi, spiders, dung, and litter.
